𝗨𝗻𝗶𝘁 𝗧𝗲𝘀𝘁𝘀: Perfect for Isolated Functionality
Unit tests in WordPress focus on individual functions or classes, ensuring each one works as expected.
🟢 Fast Execution: Ideal for CI/CD pipelines when working on themes or plugins.
🟢 Granular Debugging: Pinpoint errors quickly by testing isolated code.
🟢 Reusable Logic: Validate core functions and hooks like add_filter() or add_action().
Example:
Testing a custom function in your plugin:
class MyPluginTest extends WP_UnitTestCase {
public function test_custom_function() {
$result = my_custom_function(‘input’);
$this->assertEquals(‘expected_output’, $result);
}
}
Tool: Use the WordPress PHPUnit framework for setting up your testing environment. https://lnkd.in/dQUmf8PP
𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻 𝗧𝗲𝘀𝘁𝘀: Validate Component Interactions
Integration tests ensure different components in your WordPress setup (e.g., plugins, database, and themes) work together seamlessly.
🟢 Test Real Scenarios: Perfect for validating workflows like form submissions or API integrations.
🟢 Ensure Compatibility: Check that your plugin plays well with other plugins or themes.
🟢 Catch Complex Bugs: Identify issues arising from the interplay of multiple systems.
Example:
Testing a user registration flow:
class UserRegistrationTest extends WP_UnitTestCase {
public function test_user_registration() {
$user_id = wp_create_user(‘testuser’, ‘password123’, ‘[email protected]‘);
$this->assertNotEmpty($user_id);
}
}
Tool: Use PHPUnit and mock WordPress functions for controlled testing scenarios.
